Big Bang
We don’t know what happens inside a black hole. We only know that it produces a curvature of space where enters the exact components of our universe, matter, energy and radiation. I mean, is that you may see the hole black which is in the center of the milky way could be accumulating the ingredients to form a Big Bang at a point far away from our universe. To attract as much matter, and since the beginning of his life, a black hole would be extending this tunnel to take the subject, increasing its severity, to reach a saturation point where the end of the tunnel opens elsewhere in space to release this matter accumulated in a large explosion: the Big Bang. Obviously that this would happen in a very long time. Although there is no time in the confines of a black hole. Also, as there has always been the time (according to these hypotheses), this phenomenon can occur.
But if we start to think, the amount of matter and energy that would get a black hole wouldn’t be enough to generate a big bang, since it requires a lot more stuff. What could happen is intersection of several holes of worm, which overlap, join to accumulate more stuff, giving possibility to the singularity. This gives rise to a multi-generation of big bang at different points in the universe. This could be the response from the beginning of our universe. From here it emerges that, going back to the beginning of this text, there would be an end to our universe. I mean when I say our universe to matter and energy product of the big bang. While the expansion is inevitable, there is a big rip will depend on the distance that separates our universe of the parallel universe (when I say parallel universe I mean another portion of isolates of our universe, where may be found or not the black hole that gave rise to our big bang) nearest; If the distance is so great that gives time to that gravity is lost, there will be a big rip, although incomplete, since the inertia of the remaining particles would have the time needed to traverse the space that lack them to find a parallel universe; now, if the distance permits, limits (and here if we can speak of a limit) materials, after a certain time, you would find with the matter in a universe with that interaccionaria. This interaction could produce explosions, merger of galaxies, among many other things. But it won’t be the end and it is clear then that discarded the idea of a big crunch.
